■ L6-04: Torque Detection Selection 2
No.
(Hex.)
Name Description
Default
(Range)
L6-04
(04A4)
Torque Detection Selection 2 Sets the speed range that detects overtorque and undertorque and the operation of drives (operation
status) after detection.
0
(0 - 8)
The drive detects overtorque if the motor current or output torque is more than the level set in L6-05 [Torque
Detection Level 2] for the length of time set in L6-06 [Torque Detection Time 2]. The drive detects undertorque if the
motor current or output torque is less than the level set in L6-05 for the length the time set in L6-06.
0 : Disabled
The drive will not detect overtorque or undertorque.
1 : oL @ Speed Agree - Alarm only
The drive detects overtorque when the output frequency aligns with the frequency reference. Detection does not occur
during acceleration/deceleration. The drive outputs an oL4 [Overtorque Detection 2] and operation continues.
2 : oL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL4 and operation
continues.
3 : oL @ Speed Agree - Fault
The drive detects overtorque when the output frequency aligns with the frequency reference. Detection does not occur
during acceleration/deceleration. The drive outputs an oL4 [Overtorque Detection 2] and operation stops.
4 : oL @ RUN - Fault
When the Run command is enabled, the drive constantly detects overtorque. The drive outputs an oL4 and operation
stops.
5 : UL @ Speed Agree - Alarm only
The drive detects undertorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs a UL4 [Undertorque Detection 2] and operation continues.
6 : UL @ RUN - Alarm only
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL4 and operation
continues.
7 : UL @ Speed Agree - Fault
The drive detects undertorque when the output frequency aligns with the frequency reference. Detection does not
occur during acceleration/deceleration. The drive outputs a UL4 and operation stops.
8 : UL @ RUN - Fault
When the Run command is enabled, the drive constantly detects undertorque. The drive outputs a UL4 and operation
stops
■ L6-05: Torque Detection Level 2
No.
(Hex.)
Name Description

(Range)
L6-05
(04A5)
Torque Detection Level 2 Sets the detection level for Overtorque/Undertorque Detection 2. In V/f control, drive rated output
current = 100% value. In vector control, motor rated torque = 100% value.
150%
(0 - 300%)
Note:
Overtorque/Undertorque Detection 2 cannot set the detection level for the analog input terminal.
■ L6-06: Torque Detection Time 2
